FORD FUEL RAIL REMOVAL PROCEDURE WITH DIAGRAMS
Fuel Injection Rail Replacement Ford Super Duty 1999-2007
The fuel rail on a 6.8L is a little easier so I am attaching the process below. There are going to be some similarities so watching that video is good info just not exact steps for your vehicle.
Please see the attached info and let us know if you need more detail. This is for the non-biofuel so let me know if you have the biofuel engine and I can attach that as well but that is a rare engine.
